The diagram below shows the process by which bricks are manufactured for the building industry.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
» Write at least 150 words.
Sample Answer 1:
The given diagram shows the process of brick manufacturing in different stages for the building industries. As is presented in the diagram, brick manufacturing involves about 7 steps including the digging stages to delivery stage.
As is given in the graph, the first step of brick manufacturing is digging the clay with a large digger. This clay is then filtered and processed in a roller machine and then mixed with sand and water. In the third stage, the mixture is either kept in a mould or cut in a wire cutter to make the raw shape of the bricks. In the next stage, the shaped raw bricks are dried for 24 to 48 hours in drying oven. After that, the dried raw bricks are kept in kiln both in moderate and high temperature in up to 1300 degree centigrade and then placed in a cooling chamber for about 48 to 72 hours. This process makes the brick to be packed and delivered in the final two steps. The delivery process is the final process of brick manufacturing and as it is observed, brick making is a moderately complex process that requires some predefined stages to make it deliverable.

Model Answer 2:
The provided diagram gives information about the manufacturing process of bricks for construction.
To begin with, a certain amount of clay is collected by a digger and then this goes through a metal grid and large parts of clay become small ones. They are transported to the next stage by a roller during which sand and water are added and mixed together. The mixture later either moves through a brick cutter which cuts it into many parts of the shape of brick or is placed into a mould in which the shape of a brick is formed. Afterwards, these brick-shaped parts are put into a drying oven and stay there for 24 to 48 hours. Next, they are transferred to the first kiln for heating, whose temperature is moderate, 200 to 980 C. After this, they are heated in the second kiln under the high temperature from 870-1300C. Subsequently, in a cooling chamber, they are cooled for two to three days before they are packaged and delivered to the construction sites.
To sum up, the whole process consists of generally seven steps during which the raw material is dried, heated, cooled and packaged.

Sample Answer 3:
This supplied diagram illustrates the brick manufacturing process in an orderly manner starting from the digging of clay up to the bricks ready to be delivered into the market. As is seen in the given illustration, brick manufacturing is a complex process and involves 7 stages until they are ready to be sold in the market.
The process is initiated by digging clay with the help of a heavy machinery digger. This clay is then refined through the metal grid which throws the refined clay on the rollers. Sand and water are mixed and this mixture is either moulded or cut using a wire cutter to give the bricks a raw shape. These bricks are put in a drying oven for 24-48 hours. The dried bricks are then passed to kilns with moderate (200 to 980 degree C) and high temperature (870 – 1300 degree C) and finally placed in a cooling chamber for 48-72 hours. After cooling down the bricks, they are placed on a pallet for packaging and to be loaded on a lorry for delivery.
In conclusion, the process of manufacturing bricks is a complex process which passes through several stages before the bricks are ready for use.
